Question

Quizplus · Accepted Answer

Longshore drift occurs when waves approach a shoreline at an angle, causing sediments to move parallel to the shore. Option A is incorrect because parallel wave crests do not generate longshore drift. Option B is incorrect because the presence of a rocky headland would obstruct and disrupt the movement of sediments. Option D and E are incorrect because the height of wave crests does not directly influence longshore drift.
